Fl RE-BACK FOR STO-VES.

SPECIFICATION forming part of Letters Patent No. 278,840, dated June 5,1883. Application filed January 31, 1883. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE A. WAY, of Middleville, in the county ofBarry and State of Michigan, have invented new and useful Improvementsin Adjustable Fire-Backs; and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in theconstruction of the article known as a fireback, such as are to be foundemployed in cooking stoves and ranges, by means of whichone size onlyneed be'made, which is readily and easily adjusted to the differentsizes of such stoves or ranges.

The invention consists in the peculiar construction of the device bymeans of which this adjustability is secured.

Figure 1 shows a front elevation of my im' proved fire-back. Fig. 2 is arear elevation of the same, showing the extension at each end and theadjustability to different sizes of stoves and ranges. Fig. 3 is adetail, show ing the recess and vertical breaking-grooves. Fig. 4 is asection through the line a a, Fig. 2.

In the accompanying drawings, which form a part of this specification, Arepresents a cast-iron fire-back, which is designed to fit a smallfire-box of a stove, and, so far as the front is concerned, is of theusual construction and appearance. Upon the rear side are cast two pairsof lugs, a b, the former pair being on a lower plane than the latter,whereby the tongues G and E, hereinafter described, will pass each otherwithout interfering when the fire-back is fitted to a narrow stove.

B represents a slide or a plate provided with a tongue, 0, of a slightlydovetail form in cross-section, which engages with the-lugs a, so thatsaid plate may be extended or retracted, as may be desired. D representsanother similar plate with a similar tongue, E, which engages with theother pair of lugs, 12. B forming the lugs upon the back of the plate soas to form a dovetail recess outside of the bodyof the plate itself, thelatter is not weakened thereby, as would be the case were the dovetailrecess formed in the body of the plate. These plates, it will be seen,can be readily extended to the right and left, there by increasing thelength of the fire-back to fit fire-boxes of different lengths. It willbe seen that the plates B D are provided with recesses or more' sectionsto adapt the device to fireboxes of differing depths. In the center ofthe top edge of the fire-back A a recess, f, is formed to receive a thinprojection on the back of the fire-box found in some stoves.

The front of the fire-back is also provided with vertical grooves d (1,corresponding with the sides of the recess f, adapting the section F tobe broken out when the projection on the back of the fire-box is toothick to be properly received by the recess f. By, this construction itwill readily be seen that this improved fire-back will become animmediate article of commerce, as it will enable a party to buy such adevice, which he can readily fit into his stove without the necessity ofskilled labor so to do.

I am aware of Patents Nos. 172,192, 221, 513, 222,183, 159,350, and211,192, and make no claim to the construction shown therein.

Vhat I claim as my invention is- 1. The center piece, A, provided withlongi tudinal lugs constructed to form a dovetail recess wholly outsidethe main body of said center piece, in combination with a side piecehaving a dovetail-shaped tongue to fit into said recess, having one ofits surfaces in line with the portion of said side piece that comes incontact with the back of the center piece.

2. The center piece, A, provided with longitudinal lugs to a and b b,constructed to form dovetail recesses outside the main body of thecenter piece and arranged 011 different horizontal planes, incombination with two side pieces, B and D, having dovetail shapedtongues O E, adapted to fit said dovetailed recesses, all constructed,arranged, and operating substantially as shown and described.

- GEORGE A. WAY.
